Document Summary

3 basic types: skeletal (striated), cardiac and smooth (visceral) Location: body parts with autonomic function (gi tract, uterus, blood vessels) Contraction is intrinsic (does not require nerve stimulation) Regulated and controlled by autonomic nervous system. Voluntary motions of the limbs (locomotion), require nervous stimulation. Grouped into distinct organs units = individual muscles. Striated characteristic striped pattern, due to orderly arrangement of the. Muscle fibres (myofibers) individual muscle cells (not visible) Travel the entire length of a muscle. Each fiber covered by endomysium also unites fibers together into a fascicle. Epimysium the covering of individual muscle fibers. A group of muscle fibers, a subdivision of a muscle belly. Visible when muscle belly is cut in cross section. Wrapped by perimysium surrounds the fascicles, continuous with the tendons. Connective tissue that covers the entire muscle belly (aka deep fascia) Shortening of the length of the muscle. Movement of one body part relative to another.
